[jira] [Created] (AMBARI-4255) HBase GC logs can overwrite each other

Nick Dimiduk created AMBARI-4255:
------------------------------------

             Summary: HBase GC logs can overwrite each other
                 Key: AMBARI-4255
                 URL: https://issues.apache.org/jira/browse/AMBARI-4255
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 1.4.2
            Reporter: Nick Dimiduk


By specifying an explicit gc log file, the two hbase services running on the same host can potentially clobber each other's log files. HBase's launch scripts already create uniquely named log files per process and handle their rotation. The string {{"-Xloggc:<FILE-PATH>"}} is replaced with an appropriately constructed path.

See the replacement logic: https://github.com/apache/hbase/blob/trunk/bin/hbase-daemon.sh#L156-L158
